ELECTRIC STOVE OR IRON.

Specification of Letters Patent.

Application filed November 11, 1913.

Patented' Apr. 14, 1914. serial No. 300,314. i

To all whom it may concern Be it known that I, Gus'ravu VVENZEL- MANN, a citizen of the United States, and a resident of Galesburg, in the county ot Knox and State of Illinois, have invented a new and useful Electric Stove or Iron, oit which 'the following is a specilication. f

My present invention relates primarily to the heating element for electrically heated l0 stoves, sad-irons, gridsI and similar devices, andthe principal object thereof is to generally improve the construction and to increase the utility and etiiciency of devices oi like or similar nature.

A subsidiary object is to provide a device of the character noted which will become hot in a very short time, whereby economy in electric current is subserved.

Another object is to provide means connected with or attached to the heating element whereby simplicity and economy` of -construction are attained.

Minor objects will be in part obvious and in part specifically pointed out.

In the accompanying drawings, illustrating preferred embodiments ot my invention, Figure l' is a top plan of a stove in which my improvements are incorporated; Fig. Q, :r p longitudinal central sectional view thereof, Fig. 3, a bottonrplan of the base and attached parts, .somewhat reduced with relation to Figs. l and 2; F ig. a, a side elevation of the same, similarlyfreduced5 F ig. 5, a

modification, a top plan of afsad-iroin'ren duced with reference' to Fig. 6; and Fie. G, a longitudinal section taken in thc plane oi the line 66 in Fig. 5, but enlarged with reference thereto and showing additional features Coming now to a detailed description of said drawings, and referring to each ele. lment and part thereof. where necessary, by a distinguishing reference numeral, uniformly employed, 2 designates a heating element, which in the stove is contained in the top and in the iron .contained in the bottom.

Reference is now to bc had particularly to Figs. l-4 inclusive. 8 designates the top or plate provided with an annular liange a cut away at 7, andI with an annular boss G, (i

indicate bosses projecting` from the under side of the plate and each provided with a centrally arranged threaded recess. 8, 8 indicate grooves in the face et the plate, 9

designates a projection extending inwardly 'from the boss 5.

The `stove bottom is a casting comprising a diskl() the rim ot which seats within the flange il and rests against the boss 5. lt is prcfridfid on one edge with a pocket l1 which is adapted to sustain the weight of an attacllnient plug l2, the clip 13 oi which cngages the lower wall thereof. In its edge the disk is provided with notches which permit of the passage of assembling` screws i5 which first pass through the upper ends oft suifporting legs 1G andthe terminals of which engage threaded recesses in the boss 5 of the upper casting. On its lover tace the stove bottoni is provided with a bo.\;likc projection 17 having in its side walls threaded recesses ilor the reception of assembling` screws 18 by which an L-shapcd closure 19 (which completes the box) is secured thereq to. rllhe disk bottom is eut away to provide an opening 20.

indicates an asbestos or other heato'esisting ring ruiming around the inner face ot the annular boss 5.

22 indicates one and the other terminal of a resistance coil 2li. This coil formed preferably of a thin, narrow 'convolute ribbon of any suitable metal.

26 is an insulating bushing, its smaller end seated in an aperture in the L-shaped closure 19 and its inner end resting against an L-shaped bracket :27 having an inverted eupshaped upper portion 30 provided with an eye through which a screw 28 is passed, its threads engaging a boss 6. 29 indicates a mica. washer seated in the cup BO, and 3l indicates a similar washer seated on top ol said cup, through which washers said screw 2S passes and by which it is insulated from said cup.

32 designates a terminal post, its inner end engaged with a bracket?? and its stem resting in a bushing 2G.

The elements Q6, 27, Q8, 29, 3l and 3Q are duplicated ,in elements correspondingly numbered. Screws are threaded into suitable apertures in the bracket and provide means for coiuiecting the resistance ribbon terminals thereto and thereby to the terminal postsI rlhe body portion of 'the ribbon or wire Q11 is embedded in cement 3l possessing heat-conducting and electric-insulating properties, as are also a plurality lOl) of asbestos cords 35 which are laid between proximal 'portions of said ribbon.

Considering the iron, et() designates a casting having an aperture for the reception of a screw il which engages threads of a -boss l2 in the iron-body or plate 43, which latter is hollowed out to receive and hold a heating element similar to that hereinabove described.

44 designates a top or cap and d5 ya handle.

46, 46 designate assembling screws, and il?, et?, ber washers.

ln the foregoing specification I have described two modes which may bc adopted in carrying my invention into effect, but have by no means endeavored to recite all which might be employed, the object of this specitication and the drawings herein referred to being to instruct persons skilled in the art to carry out the 'invention in the manner and form at present preferred by me; and I desire it distinctly understood that specific showing and mention by me of a modification is in no wise intended to exclude others not referred to but which are within the spirit and scope of the invention as defined in the appended claims.

Having thus described the natur invention, I claim as new:

l. A device of the character described comprising a hollow body-member to be heated, said body-provided with an annular ange, a heating element contained in said hollow body,`a disk-like bod T-member insue of my r lated from the hollow-body member and provided with a box-like projection, a closure for said projection, terminal brackets with,- in said projection, means for connecting them with the heating element, insulated bushings supported by said closure, and teri l l minal posts insulated by said bushings from said closure and electrically connected with said brackets.

2. in electric stove comprising a hollow topplate provided with an annular ange, a heating element containedin said hollow body, a lower body-member provided with a box-like projectipn, a closure for said projection, terminal-brackets within said projection, a heating element intermediate said body members, means for connecting it with said brackets, terminal posts insulated from said closure and electrically connected with said brackets, means for insulating said lower body-member from said heating-element, legs having each a groove in which the annular llange of the top rests, and means for securing` said body members and legs together.

3. A device ofthe character described coin.- prising a hollow body to be heated, said body i provided with an annular flange, heatconducting, electric-insulating material contained in said hollow body, a resistance element enveloped by said material, an asbestos cord also enveloped thereby and disposed intermediate adjacent portions of saidribbon but out of contact therewith, a pair of bosses embedded in said material, a bracket supported by said bosses and insulated therefrom, and terminal post-s engaged with said bracket.

In witness whereof l hereunto aiix my signature at Galesburg, Ill., this 6th dayof November, 1913, in presence of two subscribing witnesses.
